2729 5979 d 20 h decky /branches/network/ add networking branch  
2728 5980 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5995 d 12 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 5995 d 12 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 5995 d 16 h jermar /trunk/uspace/ Support for mkdir().  
2706 5995 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 5996 d 8 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6003 d 17 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).
 
2699 6004 d 7 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.
 
2693 6009 d 17 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 6014 d 9 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
 
2687 6014 d 10 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6014 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6014 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2678 6022 d 13 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.
 
2676 6022 d 20 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2673 6023 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2667 6028 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ The previous commit was not entirely sane.
Handle VFS_WRITE correctly when the file doesn't grow.
Handle it correctly also when the file grows.
 
2666 6028 d 11 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2664 6030 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Fix two bugs in TMPFS-side VFS_READ.  
2663 6030 d 9 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2658 6031 d 8 h jermar /trunk/uspace/srv/ VFS work.
Foundation for TMPFS-side VFS_READ and fixes in VFS-side VFS_READ.
 
2655 6034 d 14 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS work.
VFS_LOOKUP implemented.
 
2645 6037 d 13 h jermar /trunk/uspace/ Start TMPFS.
Not loaded during boot as there is a reproducible kernel panic which occurs when
both tmpfs and fat are loaded.
 
2644 6037 d 13 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.  
2643 6037 d 14 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.
 
2639 6048 d 8 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Foundation for FAT dentry comparison function.
Beware of looking at the diff or risk loosing sanity.
 
2638 6049 d 10 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6049 d 11 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2635 6051 d 11 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.
 
2629 6058 d 9 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT directory entry.
 
2628 6058 d 10 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT boot sector.
 
2627 6058 d 11 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Start VFS_LOOKUP support in FAT.
 
2619 6063 d 9 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().
 
2615 6064 d 18 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.
 
2588 6080 d 16 h jermar /trunk/uspace/ Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to
write zero arguments all the time.
 
2568 6112 d 0 h jermar /trunk/uspace/ Rename fibril_schedule_next_adv() to fibril_switch(). Rename
fibril_schedule_next() to fibril_yield(). Some fibril structures could be
uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack
member can be NULL (e.g. every thread's first/main fibril); don't do free on
these stacks when cleaning up after a dead fibril.
 
2546 6116 d 20 h jermar /trunk/uspace/srv/ VFS work.
Upon FS registration via VFS_REGISTER, the client is assigned a unique file
system handle. When generating the VFS_LOOKUP request in VFS, we also need to
pass the device handle. Add function to transform file system handle to phone.
Implement basic multi-call VFS request serialization on VFS side.
 
2543 6117 d 15 h jermar /trunk/uspace/srv/ VFS work.
Modify the protocol so that VFS and FAT (or any other FS) have to share the Path
Lookup Buffer in read-only mode.
 
2536 6122 d 11 h jermar /trunk/uspace/srv/ VFS work.

Describe the bottleneck of one VFS-FS connection in fat.c. Add a comment
outlining possible approaches.

Also in fat.c, the async_create_manager() _must_ be called as well as
async_set_client_connection(). The latter alows VFS to duplicate the connection.
Modify fat_connection() to ACK all IPC_M_CONNECT_ME_TO calls.
